Comprehensive DescriptionRead full entry
A small brown treefrog. M 20-27 mm, F 32-33 mm. Tibiotarsal articulation reaches at least the eye, sometimes widely beyond snout tip. Hand with some webbing, foot webbing 1(0.25-0.5), 2i(1), 2e(0-0.5), 3i(1), 3e(0), 4i/e(1.25-2), 5(0.5). Dorsal skin smooth. Colouration very variable, usually brown or reddish brown, often with a dark hourglass marking and sometimes with a light vertebral stripe, a rare pattern in arboreal frogs. Lichen-like pink patches can be present in some individuals as well. The iris is yellowish or light brown in the north-eastern populations but usually has red colour in the outer iris area of specimens from eastern and south-eastern Madagascar. Ventrally white.
Tips of fingers and toes circularly enlarged. The tibia is clearly longer than the foot. Vomerine teeth are present. A nuptial pad is recognizable on the first finger. Bones are very slightly green. The skin on back, legs, and throat is smooth, on the venter slightly granular. Colour in life, light brown on the back with indistinct remains of a darker hourglass-shaped marking and many small dark spots. Dark crossbands are present on the legs. The belly is centrally silvery white and laterally transparent. The throat is transparent. In preservative the colouration of the back has not changed substantially.
Similar species: Mainly B. blommersae.
Variation: Some uncertainty surrounds the identity of the type series of this species, from Marojejy, with the populations typically adscribed to this species. More field data are necessary, but available evidence indicates the existence of more than one small Boophis species with whistling calls in north-eastern Madagascar.
Derivatio nominis: Named after the type locality, the Marojezy mountains.
